Product Description
        FB21 series paddle flow switch is mechanical type flow switch. Built-in paddle supported by reed. When the flow rate reaching the set value, the mechanical structure trigger micro-trigger switch .The setting value is adjustable. The mechanical part isolate with electric part totally
      Flow switch be mountedin a horizontal pipe line or vertical pipeline.Mount the instrument in a section of pipe where there is a straight run of at pipe diameter ≤ 40mm on each side of the flow switch.
      Padle flow switch is applied to measure the liquid flux passing through the pipeline. The liquid includes water, ethylene, glycol, or other liquid which is not hazardous to brass, phosphor brass and seal capacity. This flow switch commonly used where the interlock or shut-off place is needed.

1.It can online installation
2,.With extremely small pressure loss    
3.Good repeatability  
4.With high anti-stain ability
5.Accurate switch set up through knob 
6.The mechanical part isolate with electric part totally .
7. Have the characteristics of high precision, good stability, long working life and high reliability 

        These switches are used to detect the incoming flow or movement of the existing liquid in the pipe. They are widely used for applications like servicing water systems, heating systems, air conditioning etc  
          Suitable for industrial automation / mechanical equipment/compressed air industry /refrigeration and air- conditioning. Suitable for the diameter≤40mm pipe .
